What are Call, apply and bind methods, what is currying in JavaScript, closure , promises, hoisting, event Loop, restructuring.

Question

Accepted Answer

Call, apply, and bind are methods used to manipulate the context of a function. Currying is a technique to transform a function with multiple arguments into a sequence of functions with single arguments. Closure is a feature that allows a function to access variables from its outer scope. Promises are objects used for asynchronous programming. Hoisting is a behavior where variable and function declarations are moved to the top of their containing scope. Event loop is a mechanism that allows JavaScript to handle asynchronous operations. Restructuring is a typo, it should be destructuring.

Call method invokes a function and allows you to pass arguments individually.
Apply method invokes a function and allows you to pass arguments as an array.
Bind method creates a new function with a specified context and any additional arguments.
Currying is achieved by transforming a function that takes multiple arguments into a sequence of functions that take one argument.
Closure allows a function to access variables from its outer scope even after the outer function has finished executing.
Promises are objects used for handling asynchronous operations. They can be in one of three states: pending, fulfilled, or rejected.
Hoisting is a behavior where variable and function declarations are moved to the top of their containing scope during the compilation phase.
Event loop is a mechanism that allows JavaScript to handle asynchronous operations by continuously checking the call stack and task queue.
Destructuring is a feature that allows you to extract values from arrays or objects into distinct variables.
